The circle is inscribed in the triangle. find the perimeter of the triangle. a. 56 in. b. 60 in. c. 64 in. d. 66 in.

check the picture below.

as you can see on the example on the left-side there, two tangent lines to a circle, by the time they intersect each other, they have the same length, x = x, z = z and y = y, because they're tangent to that circle and are intersecting.

therefore, the missing part in this circle is 8, as you see there in the right-side.

so the perimeter is 24 + 22 + 18.

sina-sinb

cosb+cosa

tana-tanb

cos0+cos x pi/3

20tan

look at the picture i have filled out a table for it. hope this .
